Pronation correction

ABSTRACT

Overpronation of a foot is limited and corrected by a footwear article that acts on a foot in motion to act in relation to foot stepping by use of vertical restraints to move the calcaneus bone in a medial direction and shift pressure of the stepping foot and pull the first metatarsal laterally and shifting pressure off the first medial side to its lateral side.

FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to footwear with usage in correctingover-pronation difficulties and for other purposes.

The varieties of human feet have characteristics that often times fallinto identifiable groups. People often identify themselves by theirassumed deficit. The most common ways to identify people with pronationpropensities are as either overpronators or an oversupinators. The morecommon is the overpronator. A degree of pronation is good for humans.Most people have pronating and that does not cause discomfort. Somepeople have feet that overpronate. This is a degree of pronation on themedial side at the ankle between foot and the leg bones that isgenerally assumed to be beyond about 15 degrees of pronation. For thosewhose feet do cause discomfort from overpronation there are a multitudeof devices in the marketplace. The most common are foot orthotics placedinside footwear to diffuse, mitigate and or eliminate the discomfort.Whether over the counter or prescribed by a podiatrist such orthotics donot provide a corrective function for overpronation. Customaryprescribed orthotics for overpronation build up material on the medialside, as opposed to the lateral side of an orthotic device. This deviceis placed inside footwear and can be moved by the user to differentfootwear. This buildup of material is often called a medial “post”.

Runners who overpronate often wear motion control running sneakers.Motion control sneakers often have areas of firmer material on themedial side of the foot than on the lateral to make that side of thefoot harder to compress. It is thought this type of footwear may retardpronation on the medial side of the foot. Many types of footwear have astiff plastic material under the medial arch of the foot. The premise ofproviders is that the connection of the rear of the foot to the forefootby this stiff plastic may decrease the amount of collapse on the medialside of the shoe by the arch of the foot. However, motion controlfootwear does not provide a corrective function for the foot.

Each individual human foot adapts to bipedal walking in its own way.Currently whatever way a foot adapts to walking is unique to theindividual. Interventions to correct adaption are limited and only occurwhen bipedal walking is greatly impeded. As a result there large varietyof non-corrective devices for limited foot pain. Relief may be limitedas the foot adapts to the orthotic, but may return as these devices arenon-corrective. Consumers often try many different ones in hopes ofeliminating recurring foot pain. These include a wide variety of overthe counter models and those orthotics prescribed by professionals.

Pronation includes a rocking of the calcaneus as it touches down. Apoint on the rear of the foot initiates the rocking and the calcaneuswith talus bone above in combination bow out. The two leg bones abovethem are the top part of the bow. If the medial bowing is over 15degrees it is considered over-pronation.

This bowing point between the talus bone and the leg bones can beconsidered a fulcrum point, as in a see-saw. The posting effect oforthotics does not lift the foot at the fulcrum, but lifts by elevatingthe medial side under the foot. With these orthotics some weight isshifted laterally. This has remarkable results for those who can benefitfrom this weight shift that may even decrease the angle of pronation.Realignment of the foot for over-pronators by over the counter orprescribed orthotics provides a viable solution for many, but seems tobe limited to orthotics with arch support and or posts only. Providing asimilar function to the over-pronating that does not benefit from theseorthotics is beneficial.

SUMMARY OF THE INVENTION

An approach for overpronators used in the present invention is to limitthe calcaneus from shifting too much laterally during touch down impact.It is possible to hold the rear of the calcaneus from moving laterallywith a non-invasive device or even over time move it medially. If thiscan be done the weight is placed more laterally. If the weight at touchdown at the rear of the calcaneus were moved further towards the lateralthe result in the rear calcaneus as (this can lessen) the angle ofpronation. Further changes are required to augment this shift. The moveof the weight of the calcaneus more towards the lateral side can shiftit closer to the weight placement of non-pronators. Further, the shiftin weight placement to the lateral can shift the fulcrum of the see-sawof the wobbly calcaneus and talus combination further towards the medialand decrease the angle of pronation.

With the shift of weight to the lateral and the move of the calcaneusmore toward the medial side the performance of the calcaneus changes.This new distribution of weight and position of the calcaneus may assumean action similar to orthotic posts prescribed by professionals andorthotics sold over the counter to consumers. As this shift is to thebone of the foot it does not wear out as might an orthotics.

Further a movement of the calcaneus to the medial side may elevate itmedially as well, mimicking the action of the elevated orthotic post.With a medially elevated calcaneus the weight of a footstep of the footmay shift more towards the lateral side. This shift may begin alessening of pronation in the overpronator.

The height and angle of this elevation provides a force that effects thebones around it that may have been lower before the elevation. Theweight is shifted towards the lateral as with a post. In the correction,when the calcaneus moves to the medial the resulting elevation is notunder the foot, as with a post or motion control footwear, it is at thefulcrum of the see-saw. Further as the calcaneus bone lifts it twiststhe subtalar axis towards the lateral by shifting the position of thetalus. The twisting pushes the navicular bone on the medial sidelaterally and those in front of it; the cuneiform and metatarsals aswell. It pushes the cuneiform and metatarsals in different degrees tothe lateral and maybe the first metatarsal stays the same, moveslaterally or medially. The unpredictability of the movement of themetatarsals indicates the idea of achieving bipedal balance later in theevolutionary process through their interaction with the calcaneus as theaction of the foot triangulates. The length of the longest metatarsal,the fifth, on the lateral side possibly makes it the most important forbalance. Giving it a stronger position in bipedalism. An early problemwith bipedalism was the upper leg and torso pushing the calcaneustowards the lateral. With this device, as with the digging in of thecalcaneo-cuboid joint in bipedalism the calcaneus begins to exert moreopposability with the subtalar axis and the placement of the talus. Whenthis happens the journey to bipedalism can move forward. If this happenswith the device the movement of the calcaneus is far enough towards themedial it shifts weight towards the lateral and it can better bear theweight above it. This may find the rear of the foot in what may becalled a neutral position. This can result in a foot correction that issimilar to non-corrective solutions already in place for over-pronation.Unlike posting in prescribed orthotics there is a shift in the placementof the bones of the foot, not just a raising of a medial portion orportions of the foot. Similar to posting with the invention the archarea is raised, but from within the bone structure, rather than underthe foot. The lifting is at the fulcrum of the see-saw. As the liftingis done with the calcaneus bone it is more permanent that with man-madematerials. The lifting brings about favorable changes that may lead to alessening of pronation in over-pronators. This shifting of the calcaneustowards the medial has consequences and may need further action to thefoot in motion to adapt the footstep to this correction.

Among these consequences is a shift of the remainder of the foot farthertowards the lateral side. Similar to a portion at the lateral calcaneusand the medial a portion of the device may be placed beside the firstand fifth metatarsals. This may require a further exploration andunderstanding of human evolution towards bipedalism that developed in asimilar way.

The device can follow a similar track taken by evolution and also beginat the rear of the foot and then move the remainder of the footlaterally. Evolution took over a million years of this approach toachieve the extraordinary result of human bipedalism. A human lifetimeis relatively inconsequential in relation to changes occurring inevolutionary time. Evolutionary changes in individual humans do notnecessarily manifest at the same time. These differences are often foundin the variety of configurations of the human foot. The human footcontains twenty six bones and it must be remembered our ancestors theape, gorilla and chimpanzee foot often contained the same amount ofbones. These same twenty six bones provided them with entirely differentfunctions than us humans. Later on in evolutionary time there werevarieties of homo sapiens ancestors including species ofaustralopithecines with the same amount of bones that were unable tomake the jump to bipedalism similar to humans.

The journey of the device begins at the calcaneus and the evolutionaryshift to bipedalism began with the calcaneus and cuboid hone on thelateral side of the foot. The locking of this joint called thecalcaneo-joint began many changes in the primate foot over anevolutionary timeframe of a million years that resulted in humanbipedalism. Emulating evolution one can begin at the calcaneo-cuboidjoint. Moving the calcaneus to the medial side would require astiffening of footwear at the lateral side that is greater than thestiffness of the material on the medial of the device opposite thelateral. A stiffening of the material at the lateral side of the footmay bio-mimicry the action of the locking calcaneo-cuboid joint thatbegan human bipedalism.

As apes, gorillas and chimpanzee became less arboreal the musclesassociated with the grasping of the opposable first and second, thirdmetatarsals weakened. Their position weakened further as primates leftthe trees and the strong muscles needed for grasping with their feetdiminished further. The evolutionary locking action of thecalcaneo-cuboid joint towards bipedalism occurred through the weakeningof the muscles. Diagonally opposite to the grasping of the opposablefirst and second, third metatarsals of the ape, gorilla, chimpanzeeprimate foot is the force of the action of the locking calcaneo-cuboidjoint that, like the opposable first and second, third metatarsals ofthe apes dug in, strengthened and eventually determined the outcome ofhuman bipedalism.

In front of the cuboid bone on the lateral side is the base of the fifthmetatarsal. Opposite it on the medial side is the first metatarsal. Theshift to human hipedalism required a reconfiguring of the human foot tomore of a triangular shape. Through the motion of first and fifthmetatarsals to both bear weight and retain balance they led the way tothis shift through there interactivity, and with that of the calcaneusand calcaneo-cuboid joint moved toward human bipedalism.

The three points; the calcaneus, the first and fifth metatarsals make upthe triangle of the human foot that resulted in human bipedalism.Evolution then developed three arches in the human foot. Over a millionyears evolution shifted these three arches upwards and over other bonesto deposit weight, force and the need for balance at these three pointsof the foot. Similar to evolution the managing of the triangulation ofthese three points may have a positive effect on the anatomy of a humanfoot that may not have achieved the maximum benefits of evolution'sstruggle to human bipedalism.

Other objects, features and advantages will he apparent from thefollowing detailed description of preferred embodiments taken inconjunction with the accompanying drawings in which:

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Similar to the evolutionary journey to human bipedalism devices of theinvention apply compression and tension, push and pill to bring aboutchanges to the overpronator's foot. Changes and corrections to the footare achieved over time by footwear of the invention. The inventioncorrects the overpronator's foot by moving the rearfoot medially andfoot portions forward of it laterally. Shown in FIG. 1, is line 282 witharrowhead 282A pointing the direction of the foot correction. Along 282is rearfoot arrowhead 283 pointing the medial direction of vector forceon the overpronator's foot. On the lateral side of the foot medialpushing vector force 283 pushes the forefoot 284 laterally with atwisting on or about 285 in the midfoot. The vector force of footwearpushing the rear of the calcaneus to the medial interrupts the usualforward foot gait. The medial vector force also pushes forward alongline 282 engaging a twist on or about point 285 not usual to theoverpronator's gait. This forces the talus bone 279 in FIG. 1 to shift.The twist about point 285 pushes the navicular 280 laterally and thenthree cuneiform bones 281, and metatarsals 31, 32, 36, 37, 38 laterallyand medially.

The dashed line 57 in FIG. 2 parallel to 282 also shows twist 285 anduses the same oppositional forces shown in FIG. 1, arrows 283, 284 infootwear. Footwear of the invention uses oppositional forces across thefoot shown in dashed line 57 arrows to provide a correction to theoverpronator's foot.

In FIG. 2 shown is footwear of the invention—a sole insert 286 extendsdiagonally vis-à-vis the foot and having vertical tab extension of thatsole insert, i.e. substantially rigid tabs 21 and 59 restrainingrespectively, medial and lateral movements. At rearfoot impact verticaltab 59 beside the calcaneus and horizontal 286 under the calcaneus movethe calcaneus medially and sole portions 285 at midfoot along crossingline 57. The twist on or about 285 pulls up sole portion 286. On themedial side of 285 sole portion 286 continues to pull up and movelaterally. This continues to vertical tab 21. Footwear portion 21 besidethe first metatarsal is pulled laterally by the vector force along 286.Vertical tab 21 pushes the first metatarsal 32 laterally and the othermetatarsals 38, 37, 36, 31 laterally as well. By moving the footlaterally it moves weight, compressive pressure off the medial and ontolateral side of the foot.

Taking weight off the medial side of the overpronator's foot istraditionally done by orthotic posts external to the foot and prescribedby a professional. Posts raise up the medial side of the foot. They tiltthe medial side up higher than the lateral. Footwear of the inventionshifts weight, compressive pressure off the medial and onto the lateral.Footwear of the invention and orthotic posts both shift weightlaterally. The weight is moved laterally in the foot by the action offootwear of the invention. This action can be continued and graduallydiminish the overpronation with the corrective footwear and eliminatethe need for a device.

The pull up of sole portion 286 provides support to the medial arch. Thepull up of the footwear provides a correction to the overpronator's footby lifting the medial arch and forefoot areas inside the foot. Thefootwear acting on the foot bones provides a correction to theoverpronator's foot by moving portions of it up at the midfoot like anexternal material medial arch support. Footwear replaces manufacturedmedial arch supports external to the foot by providing a foot correctioninside the foot gradually over time. The footwear engages the whole footin the correction by utilizing the naturally occurring oppositionalforce along 57 crosswise across the foot. Wearing the correctivefootwear over time allows the continual pushing of the calcaneusmedially by footwear 59, 286, 21 to provide a foot correction. Using aprescribed orthotic may relieve pain, but does not provide a footcorrection.

Footwear of the invention provides a foot correction for overpronators.In FIG. 2 the corrections include: (1) the pull up of 286 supporting themidfoot, medial forefoot and first metatarsal 32; (2) the response ofthe lateral shift of 286, 21 on the midfoot and forefoot is to push themlaterally; (3) the response of 286, 21 back to 59 beside the calcaneus30, lateral 286 is to pull them in tension medially. The upward pull of286 supporting midfoot, forefoot and first metatarsal is a footcorrection of the invention as well. This can occur without 21.Adjustable portions can be added to 59, 286, 21 to gradually push andpull the foot laterally.

FIG. 3, shows a variant of the invention. At rearfoot impact lateralvertical tab 59 beside the calcaneus moves the calcaneus medially.Horizontal sole portion 287 engages the twist on or about 285 at midfootalong 57. Footwear portion 287, responds to the calcaneus' medialmovement by pulling up vertically and moving laterally. Relativelyvertical footwear portion 288 beside medial midfoot arch pulls up andlateral. The vector force of the footwear on the rearfoot calcaneusmoves it to the medial and the opposing vector force of the footwear onthe medial midfoot arch pills it up and shifts it to the lateral. Thefootwear acting on the foot bones provide a correction to theoverpronator's foot. In FIG. 3 responses of footwear of the inventionproviding a foot correction by the invention include: (1) the verticalpull up of lateral 287, 288 supporting the midfoot and medial arch; (2)the response of the lateral shift of 287, 288 on the midfoot arch is topull it laterally; (3) the response of 287, 288 back to 59, 287 is topull them in tension medially. The upward pull of 287 supporting themidfoot arch is a foot correction of the invention as well. This canoccur without 288. Adjustable portions can be added to 59, 287, 288 togradually push and pull them laterally.

FIG. 4 shows footwear of the invention with FIG. 2 structure above FIG.3. It is understood FIG. 3 can be above FIG. 2 structure. Footwearfeatures of FIG. 2 and FIG. 3 mentioned above are applicable to FIG. 4.Footwear is along crossing line 57. Vertical tab 59 beside the lateralcalcaneus pushes it medially. Relatively horizontal sole inserts 286,287 move forward under the foot with a twisting action on or about axis285. Footwear portion 286 moves forward of 287 and under the firstmetatarsal and to 21 beside it. FIG. 3, footwear portion 287 moves tomedial midfoot portion 287 under the medial arch and to 288 beside it.The combination of FIG. 2 above and FIG, 3 under increases the thicknessof the material in the rearfoot where FIG. 2 covers FIG. 3. Thisaddition of material may improve the ability of the lateral footwear 59,286, 287 to move the rearfoot medially. The lesser material incomparison at the midfoot arch and first metatarsal may provide moretension, flexibility at the medial midfoot and forefoot. FIG. 4 footwearshows adjustable portions 289, 290. Footwear shows two plugs 289protruding upward from 287 in FIG. 3. Two of the eight holes 290 in 286in FIG. 2 contain the plugs. FIG. 4 is adjustable allowing the wearer tomove it farther forward, backward and to the lateral side. It isunderstood rearfoot lateral 59 can be part of one or the other of FIG. 2or FIG. 3. It is understood footwear can have adjustable portions alongline 57 at the calcaneus 30, medial arch and 21 at the first metatarsal32. FIG. 2 can be combined with FIG. 3 into a single piece device withand or without an adjustable portion. It is understood there are manyways to make footwear of the invention adjustable.

The material used in footwear of the invention i.e. horizontal soleinserts with vertical tab extension thereof integral therewith, the tabsextending from about 0.5 to 2 inches from the horizontal sole portionand in any event sized and sufficiently rigid to perform the patentfunctions and is generally a hard material. The combined oppositionalforces of the invention push bones in compression and absorb shock tothe foot pulling in tension. The material must be able to direct bonesof the foot with compression, absorb shock and respond in tension.Commonly available Carboplast brand and other brands of carboplasticsheets (thermoformable fiber reinforced plastic sheets) are examples ofsuitable material. The material thickness can be in a range fromapproximately 1.5 mm to approximately 4 mm. The layering of material inFIG. 4 appropriately increases the thickness at lateral rearfoot impactwhere direction and control of compressive force is needed. At themedial arch and forefoot the single layers of material thereappropriately provide more flexibility to absorb shock and respond intension. Thickness of material, flexibility and rigidity can bedetermined according to the compressive vector forces on the footwearrequired to impart a correction to the overpronator's foot whileallowing the material to respond in tension. The structural design andlight weight thin material usage of the footwear in the presentinvention is in contrast to footwear materials that provide cushioning.

Unlike the parent application all footwear of the present inventionincluding FIGS. 2, 3, 4, 5 utilize the vector force of rearfoot impacton rearfoot lateral footwear portions to activate a footwear correctionfor the foot.

FIGS. 2, 3 are different from my parent applications cited above atparagraph [0001] as there only two features are placed diagonally acrossthe foot along crossing line 57 in different zones; FIG. 2 in rearfootand forefoot, FIG. 3 in rearfoot and midfoot. FIG. 4 is different fromthe parent application as there three features are placed diagonallyacross the foot along crossing line 57 in different rearfoot, midfootand forefoot. The parent application with two features are in theforefoot zone only. The parent application has no footwear portions atthe midfoot medial.

Using only two diagonal features allows this invention to apply impactforce to the rearfoot feature along crossing line 57 to exert control onthe opposite sides, across the foot to shift the foot hones. The impactforce redirects foot portions along crossing line 57 to provide agradual correction over time to the overpronator's foot. In the parentapplication there two features are only in the forefoot.

FIG. 5 in the present invention uses rearfoot impact along crossinglines 57, 58 to, in part spread the foot laterally and push it laterallyrather than contain, hold and sustain the foot as the parent applicationdoes. The use of three or more features in the parent application relieson sustaining the footwear rather than correcting with vector force.

Reference is made to the footwear invention described in thisapplication may be considered and compared in relation to the footweardescribed in my prior U.S. patent applications, Ser. No. 13/949,651filed 24 Jul. 2013; Ser. No. 13/355,622 filed 23 Jan. 2013; provisionalapplication Ser. No. 61/649,373 filed 20 Oct. 2011; and my PCTapplication Ser. No. PCT/US12/54075 filed 7 Sep. 2012 and provisionalapplication 61/939,910 filed Feb. 14, 2014, the content of all of whichare incorporated by reference as though stated at length herein. SeeAppendix A and Appendix B hereto.

FIG. 5 shows what may be called a “cross” or “X” shape of diagonaldashed lines 57, 58. The “cross” or “X” shape 57, 58 with two headedarrows indicates countering diagonal forces across the foot. Footwearportions along crossing line 57 are 59, 293, 21 and are under footwearportions 60, 294, 50 along crossing line 58. It is understood 57 can beabove 58. On or about 285 in FIGS. 2, 3, 4 under the foot in FIG. 5 isplaced adjustable portions 291, 292, Footwear portions 58 octagonalpolygon hole 292 is placed over 57 octagonal polygon plug 291 as anadjustable to place footwear at different angles to provide a footcorrection for the overpronator. It is understood there are many ways toprovide an adjustment to footwear of the invention. The dashed lines 57,58 are in opposition to each other. Their opposing forces are used toadvantage to work together in FIG. 5 to provide a foot correction to theoverpronator's foot. Along crossing line 57 lateral rearfoot verticalfootwear 59 at the calcaneus pushes medially and along 293 forcingforefoot vertical footwear 21 to push laterally. Along crossing line 58medial rearfoot vertical footwear 60 at the calcaneus pushes medially toaccommodate the medial push of 59. Footwear portion 294's medial pushalong 58 forces forefoot vertical footwear 50 to push laterallyaccommodating the lateral push of 21. Crossing line 57 provides thecompressive force to move the foot laterally and crossing line 58accommodates 57 in the rearfoot 60 and forefoot 50. Crossing line 57requires relatively greater strength of material than 58.

As the foot correction begins and continues adjustments can be made tothe lateral side of the footwear as the forefoot moves laterally. Thefifth metatarsal 31 with the cuboid 40 adjusts balance and acts intension, milling the rest of the forefoot laterally. In the invention,lateral portion 50 in FIG. 5 of the footwear can push the fifthmetatarsal 31 in FIG. 1 towards the lateral. The fifth metatarsal 31then pulls the remainder of the metatarsals laterally. During the footcorrection footwear accommodations are made at the fifth metatarsal 31and overpronators achieve a new balance. Forward lateral footwearportion of 50 in FIG. 1 by the base of the fifth metatarsal 31 istwisted and shifted toward the lateral. This increases the angle ofportion 50 to accommodate the movement of the metatarsals laterally andthe increased foot action at this triangulation point as the footcorrection continues. The rearward part of 50 is not twisted and shiftedas much at the base of the fifth metatarsal 31. When in use rearwardportion of 50 at the base of fifth metatarsal 31 pushes the base of thefifth metatarsal 31 at a wider vector force angle that assists the shaftand the head of the fifth metatarsal 31 to pull out to the lateral. Thislateral push at the base of the fifth 31 by the rearward footwearportion of 50 forces the fifth metatarsal 31 to pull with it in tensionthe other metatarsals laterally to achieve a new balance for theoverpronator's foot.

It will now be apparent to those skilled in the art that otherembodiments, improvements, details, and uses can be made consistent withthe letter and spirit of the foregoing disclosure and within the scopeof this patent, which is limited only by the following claims, construedin accordance with the patent law, including the doctrine ofequivalents.
